The Addison All Products Guide 2024 delivers a thorough, manufacturer‑direct overview of Addison’s complete lineup of dedicated outdoor air systems (DOAS) and mission‑critical cooling solutions. As a company with a 75‑year legacy of engineering innovation, Addison provides a clear snapshot of its approach to sustainable HVAC design, adaptable system configurations, and technologies that lower total cost of ownership. This guide highlights the depth and versatility of the Addison portfolio, helping engineers, facility managers, and building decision makers evaluate high‑performance HVAC solutions for commercial and mission‑critical environments with greater confidence and clarity.
Key Topics, Applications, and Takeaways
The resource explores multiple product families, each supporting different airflow needs, capacity ranges, and application requirements. The PR and AK Series cover capacities from 3 to 140 tons and airflow from 400 to 22,000 CFM, offering features such as 2” double‑wall foam‑insulated construction (R‑13), 6‑row intertwined DX coils, modulating electric or gas heat, and optional FrostShield® technology for frost‑free heat pump operation. These units are available in both air‑source and water‑source heat pump configurations, supporting a variety of ventilation, dehumidification, and comfort‑cooling applications. The guide also details compact footprint options, vertical or horizontal discharge configurations, and advanced features such as switchable subcooling circuits—allowing design teams to match equipment performance to project constraints.
For more specialized installations, the MI Series introduces modular indoor systems with a design flexible enough to fit through a standard 30″ doorway. This makes them well‑suited for retrofits or confined mechanical rooms. Modular units can be tailored for dedicated outdoor air, mixed air, or recirculation needs, and are available in both air‑source and water‑source heat pump configurations. Galvanized steel construction and the use of 6‑row DX coils reinforce durability and reliable long‑term operation. For applications requiring hybrid performance, certain models are available with Addison’s HybridAir™ technology, broadening their versatility even further for diverse building requirements and engineering objectives.
The guide also covers the MARV Series, MARS Series, and MI Classic (WI) systems—unit categories that provide additional configurations for outdoor air handling, recirculation cooling, and dehumidification needs. These systems feature airflow ranges from 500 to 15,000 CFM and capacities from 3.5 to 80 tons, with optional heat pump operation and modulating reheat circuits. Pairing options with the MC Series condenser add further flexibility for project‑specific requirements.
For mission‑critical facilities such as data centers, Addison offers high‑precision self‑contained DX systems with capacities from 35 to 435 kW and airflow between 4,000 and 60,000 CFM. These units support upflow, downflow, and ducted airflow arrangements, enabling integration into diverse room configurations. EC fans and advanced controls help maintain stable, efficient performance in environments where uptime is essential. The CDU Series expands mission‑critical support with cooling distribution capacities from 400 kW to 2 MW, multiple pump options, stainless‑steel internal piping, and customizable dimensions—bringing resilience and adaptability to liquid‑cooling applications across modern technology infrastructure.
Who Should Use This Resource and When
This resource is exceptionally useful for mechanical engineers comparing product families, facility managers evaluating upgrade paths, and decision makers planning HVAC infrastructure for new construction or modernization. Because the guide includes manufacturer‑verified data—such as airflow ratings, capacity ranges, coil configurations, and construction details—it streamlines early‑stage planning and helps project teams narrow their equipment selections with confidence. Anyone working on ventilation, dedicated outdoor air integration, dehumidification control, or mission‑critical cooling will find practical value in the document’s structured, informative format which supports more efficient decision‑making overall.
